He received an M.S.P.H. in Environmental Science and Engineering from the University of North Carolina and a Ph.D. in Ecology from the University of Georgia, doing research at the Coweeta Hydrologic Laboratory. He was later an Assistant Research Professor at Duke University, working on biogeochemical cyclesintheEvergladesofFlorida. HehastaughtcoursesinMicrobialEcology, WetlandEcology and Management, Forest and Range Soils, Soil Genesis and Classification, Natural Resource Ecology,Biodiversity,ConservationandHumans,andEcologyofFlowingWaters.Aftersomeearly research work in ultraviolet light disinfection of bacteria and viruses, and kinetics of reactions of oxidizing chlorine with humic substances, his research work has centered on biogeochemistry of forests,wetlandsandstreams.Thisworkhasincludeddissolvedorganicmatterdynamics,primary succession and soil organic matter formation, root production during succession, formation and decompositionofhumicsubstances, proteincontentindissolvedorganicmatter, bioavailabilityof NandPinriversandlakes,andecophysiologyofinvasiveplants.Dr.QuallshasalsobeenaVisiting ProfessoratYokohamaNationalUniversityinJapan.Hereceivedthe“PioneerofDisinfectionAward” from the International Water Association and the Water Environment Association.

Onthe otherhand,theCO2 fertilizationeffectmaypartiallyoffsetlossesofsoilorganicmatter,butmany havequestionedtheabilityofNandPstockstosustaintheCO2fertilizationeffect. Despite many advances in the understanding of C, N, and P cycling in forest soils, many questions remain. For example, no complete inventory of the myriad structural formulae of soil organicNandPhaseverbeenmade.

The16papersinthisbookcoverageographicallydiverserangeofforestecosystemsonfour continents. The studies also cover a range of forest types: tropical rainforest, tropical savannah, subtropical mixed deciduous and needleleaf forest, temperate broadleaf and needleleaf forests, subalpineandalpineneedleleafforests, borealneedleleafforest, aswellastropicalandtemperate forest plantations. The chapters are arranged by subject in the following order, those concerned largelywithcarboncycling(includingnetprimaryproductivity,soilorganicmatter,andgreenhouse gasses),microbialecology(communitycompositionandenzymeactivity),andNorPcycling.
